get a tape messuer under the car :-p easyest way and you will know that your getting the right pipe, why dont you make your own though, 45quid or what ever the decat cost is alot for a pipe with a small bend in it, if you can weld open your old cat up and strip it then weld it back up, it might sound a bit like a bean can but it will be a decat with a hole for the lamba sensor

i bought the milltek decat n it bolted to my existing magnex exhaust but i had to use the old sleeve that came off the cat to fit it which u may have to do, i wasnt given a size just told it would fit lol, my exhaust is no bigger than the original coming out of the cat tho so u shouldnt have a prob.

hold on just rememberd, milltek came with a sleeve that extended to the original sleeve so dnt know if what ur lookin at buying will cum with one so probably the 710mm.
